Managing Kubernetes costs can be a daunting task, especially now with the prevalence of multi and hybrid-cloud computing environments. Implementing Kubernetes environments correctly can help make this process smoother and easier, especially when it comes to managing your ephemeral environments.
One of the best ways to limit a Kubernetes cluster’s costs is understanding how to manage physical clusters and ephemeral environments.
Although it’s considered a best practice to organize a cluster using namespaces, it can incur additional costs when done incorrectly. While namespaces alone will not increase cost, poor namespace usage makes it harder to keep track of where costs are coming from.
Shipyard believes it is best practice to use one cluster exclusively for production and keep any other environments in a separate cluster. This gives your team room to experiment and make mistakes, while ensuring your production environments will not be affected by lower-priority ones. While this sounds like it’d be less cost-effective, isolating two clusters with very different tolerances/profiles will allow for more targeted cost management in each.
What is the best way to manage your Kubernetes clusters? Well, that depends on who you ask. In our opinion, a good starting point is looking at the cluster’s size. In general, the number of microservices running in a cluster is a relatively straightforward way to get an idea of your deployment’s size.
